If you draw a figure n take any 4 points, you get 8 regions

if you take 5 points you get 14 regions

I dont know how you will draw the relationship , cos i dont think there is any.

There are 8 possible regions in a circle with 4 points along the circumference.

Points: 2, 3 , 4, 5

Regions: 2, 4 , 8 ,16

The formula for this is y=4(x-2), where x is the amount of points and y is the amount of poss. regions.

It is always one more region than there are points. Try placing any shape (square, pentagon, hexagon, septagon, octagon, etc) inside a circle and connect the lines, then count them.
